SAN FRANCISCO — The longest America’s Cup in history will come down to two 72-foot, space-age catamarans making a final sprint around San Francisco Bay, on a five-leg course framed by the Golden Gate Bridge and Alcatraz Island.
Skipper Jimmy Spithill and defending champion Oracle Team USA saw to that by extending their almost unimaginable winning streak to seven Tuesday to force a winner-take-all finale against Emirates Team New Zealand.
Oracle came through a wild start with two collisions to win Race 17, then sped past the Kiwis after they made a tactical error to give up the lead in Race 18.
All but defeated a week ago, Oracle Team USA tied the faltering Kiwis, 8-8, by winning its 10th race overall. Oracle was docked 2 points for illegally modifying boats in warmup regattas and Dirk de Ridder, who trimmed the 131-foot wing sail, was disqualified.
If it hadn’t been hit with the harshest penalties in the 162-year history of the America’s Cup, Oracle Team USA’s sailors would be hoisting the silver trophy in victory and spraying each other with champagne.
Instead, the epic 19th race is scheduled for Wednesday, weather-permitting.
Either Oracle will finish one of the greatest comebacks in sports history or Team New Zealand, marooned on match point for the past week, will get the win it needs to claim the Auld Mug for the second time in 18 years and ease the nerves of the 4.5 million residents of the island nation.
Oracle has made changes to its black cat almost every night in its big boatshed on Pier 80 and has learned to sail it better under the watchful eye of team CEO Russell Coutts, a four-time America’s Cup winner.
But there’s a bigger reason Oracle is still alive. ‘‘Never giving up,’’ Spithill said.
The 34-year-old Australian has been almost defiant in leading his well-funded, deep team after it was penalized just four days before the sailing began.
‘‘I really feel it’s because we've been through such hard times in this campaign that it’s prepared us for this situation,’’ Spithill said. ‘‘I spoke yesterday a lot about the capsize and stuff like that and what went on before this regatta. This team has just been through so much and some incredibly difficult times. Those were key moments, we needed those key moments to prepare us as a team.’’
Oracle’s first boat capsized in October and its wing sail was destroyed, costing the team four months of training time until a new one arrived from New Zealand.
Barker, the losing skipper in the 2003 and 2007 Cup, looked deflated after the double losses.
‘‘We got beaten today, and that’s tough to handle, but sometimes you just have to accept that,’’ he said. ‘‘It’s frustrating, but we know we can still win this, and we will go out there and give it absolutely everything we can tomorrow.’’
